I lost count of how many hours I spent trying to beat it when I played through ages ago, probably on the last gen systems, before giving up. Decided to give it a go with a hexer yesterday, and beat it on the first try. It was almost laughably easy. No more one-shot fire breath. This of course pleased me, since now Vendrick will be a pushover. Was the dragon changed for the Scholar edition, or was it later in a calibration?
